Moraes, A: Cisco Firewalls (Cisco Press Networking Technology Series)

Cisco Firewalls thoroughly explains Cisco's full spectrum of network and application firewall products, features, and solutions, and shows how they can add value to network security designs and operations. In this book, a leading Cisco security expert shows how to optimize the placement of Cisco firewalls, grouping and structuring them to build highly-secure self-defending networks. The book begins with a discussion of Cisco's classic stateful firewall solutions, including PIX/ASA, FWSM, and the IOS Firewall. Next, it covers application-oriented Cisco firewall offerings such as the ACE XML Gateway with web application firewall, and the Ironport Web Security Appliance. For each product, the author also explores tools for verifying correct operation, and for troubleshooting and resolving problems. This is the first book to show how to protect Unified Communications systems using Cisco firewalls. It also presents unprecedented coverage of firewall integration with other security elements such as IPS, VPNs, and load balancers; as well as two full chapters on IPv6 firewalls.
